Display Device

5. The display device of claim 1, wherein the hysteresis calculator divides the display panel into a plurality of blocks, calculates a representative value corresponding to each of the plurality of blocks in the image signal, and calculates the current hysteresis state value corresponding to each of the plurality of blocks based on the representative value corresponding to each of the plurality of blocks and the previous hysteresis state value corresponding to each of the plurality of blocks.

7. The display device of claim 1, wherein the hysteresis calculator calculates the current hysteresis state value based on the image signal and the previous hysteresis state value every predetermined time and stores the current hysteresis state value in the memory.

11. The display device of claim 10, wherein the hysteresis calculator and the compensator do not operate, when the image signal of the current frame is the still image signal.

15. The display device of claim 12, wherein the hysteresis calculator divides the display panel into a plurality of blocks, calculates a representative value corresponding to each of the plurality of blocks in the output signal from the multiplexer, and calculates the current hysteresis state value corresponding to each of the plurality of blocks based on the representative value corresponding to each of the plurality of blocks and the previous hysteresis state value corresponding to each of the plurality of blocks.

17. The display device of claim 12, wherein the hysteresis calculator calculates the current hysteresis state value based on the image signal and the previous hysteresis state value every predetermined time and stores the current hysteresis state value in the memory.
